It wasn't in a zelda game, but in new super mario bros. wii, I had made it to the last world. My sister was playing one day on her own save file, and she was on the file select screen. She looked in the corner and saw that the - button on the wii remote said that it would erase a file. she didn't know what that meant, so she hovered over my file and pressed it. I gave up on mario that day. I have never played a side-scrolling mario game since.
